ARFF to CSV multiple files conversions

Anyone successfully tried to convert many ARFF files to CSV files from windows Command line.

I tried to use weka.core.converters.CSVSaver but it works for a single file only.

Can it be done for multiple files?

Solution

  • I found a way to solve this conversion by using R as shown in the following Script:

    #### Set the default directory to the folder that contains all ARFF files 

temp = list.files(pattern="*.arff")
library(foreign)

for (i in 1:length(temp)) assign(temp[i], read.arff(temp[i]))

for(i in 1:length(temp))
{
mydata=read.arff(temp[i])
t=temp[i]
x=paste(t,".csv")
write.csv(mydata,x,row.names=FALSE)
mydata=0
}
